This is exactly right. Local storage is conceptually the persistent volume equivalent to an emptydir volume mount.

If you want to have a 'storage node' in a simple way, the NFS storage provider is the way to go. You install the nfs client libs on each node, setup an NFS share and configure and run the provisioner[1].

My experience with iSCSI is to stay the heck away from it. It is not what you want. iSCSI is really meant for people who already have iSCSI SANs and not people who have a disk they want to share. The more I learned about it, the more I learned that I should have picked something else for every use. It's not that it's bad, it's that it solves a much different problem than I expected given the networked nature of it.

NFS-Provisioner and NFS-Client have been around for a while. They're about to be promoted from Incubator actually.

That is fantastic, I remember when they were new ideas without any implementation but just a few people trying some things on GitHub issues.

This article does the NFS approach justice I think, I was pleased to find it has been a working strategy for a while!
